Send my new frame back?

I've recently bought a new frame that is all good apart from a small (2 inch approx) crease on the underside of the downtube by the headtube. It's parallel to the sides of the tube. It's more of a small undulation that is just visible to the naked eye but I only found it when I was running my fingers over the tubes (sexy, I know). It looks like it happened when the downtube was being curved during production.
So, what do you think, panic and send back or is it nothing to worry about?

Guilty of procrastinate confusion.
It means doing something else to delay a more important pressing task, not quite what I meant which was.... sticking your oar in on here when you should be doing something else.

My most expensive purchase from Brant broke. They did replace it but it would have been better if it hadn't broken in the first place. My other purchase from him had instant chain suck. He said it was down to the way my girlfriend changed gear. Please note she never had a problem before or since.
